Benchmark: Date JsonReviver4

Script Preparation code:

var input = [];

for (i = 2; i <= 100000; i++) {
    const date = new Date(Math.random()*1000);
  
    const value = i % 2 === 0 ? date.toISOString() : 'some random value';
    const key = i % 2 === 0 ? 'businessDate' : 'some random key';
  
    input.push({
        key,
        value
    });
  
    input.push({
        key: 'index',
        value: i
    });
  
  input.push({
        key: 'updatedAt',
        value: i
    });
}

6
const dateFields = ['businessDate', 'startDate', 'endDate', 'updatedAt'] const result = input.map(x=>{ if (dateFields.includes(x.key)) { return new Date(x.value); } return x.value; });
